I'm surprised we don't have a topic for this software yet! There's lots of communities that are powered by Discourse these days, even the official Unity forums is powered by Discourse. You can either pay for hosting if you don't want to set everything up yourself or go with self hosting, however you'll need VPS hosting and not shared hosting because Discourse relies on Docker which can only be installed on VPS hosting. I'm still slowly in the process of moving one of my forums from phpBB over to Discourse. It was pretty easy to install, but I do have some Linux knowledge. Are you using this software for your community? Have you joined a forum using this software?
